Evaluating driving from the point of view of efficiency is a complex task. The environment is continuously changing and there is no direct relationship between all the factors that affect fuel consumption. In this paper, we propose a method to evaluate driving that can fit any scenario. It is based on Data Envelopment Analysis (DEA). This technique allows us to measure the efficiency of the drivers and to ascertain which behaviors they should improve. There are many solutions to evaluate driving in the literature. However, these solutions have difficulties adapting to changes in the driving environment and the result of the evaluation could be inaccurate. A driver could be classified as less efficient when in fact the driving could be affected by factors beyond his or her control. In addition, they do not provide the sources of inefficiency. With our method, we can analyze and quantify the cause of inefficiency. This proposal has been used to evaluate drivers of a bus fleet in Spain. The results show that drivers who were rated as efficient achieve lower fuel consumption. They can save up to 9.21% in comparison with the least efficient drivers. It is also observed that anticipation is a skill that saves a large amount of fuel and that it is an aspect that most bus drivers have a lot of room for improvement.

“…This information is a unique identifier assigned by the transport company to each driver with the aim of maintaining the privacy of the drivers. A detailed description of the architecture can be found in our previous work [27]. Once the data has been stored in our system, a set of additional modules carry out actions in order to complete the learning evaluation process.…”

Interest in energy cost saving and in global warming have persuaded transport companies to apply measures to reduce fuel consumption. Efficient driving is one of the most employed solutions as it allows savings in fuel consumption of around 10% with a minimal investment. The drawback is that efficient driving is a learning process and it greatly depends on the drivers' behavior, which in turn is closely related to their motivation. If drivers are not really involved or after some time their interest decreases, efficiency improvements would disappear. Thus, an efficient driving program should make drivers' motivation one of the main targets. One option could be the implementation of reward programs. However, these should be based on a clear individual evaluation process, as an unfair system could lead to discomfort, complaints and repudiation. In this paper, we propose an analytic system, based on the detection of efficient and inefficient behavioral patterns, to evaluate the individual driver's progression in efficient driving with the aim of being the basis of a reward program. The system receives relevant, driving related, vehicle information every 1.5 seconds, allowing a precise searching of patterns. It has been tested successfully in 16 bus companies, analyzing the performance of 880 professional drivers. To accurately illustrate the analytic process, three detailed driver analyses have been included as a case study. Results of this applied research on the eco driving field show that the proposed system identifies efficient and inefficient actions that are used to fairly evaluate the drivers' performance.

Resumen-The transport sector is one of the main causes of the emission of pollutants to the environment. Among the different alternatives for reducing consumption and emission of harmful particles the most attractive for professional transport companies is the use of efficient driving techniques as it allows to take advantage of the existing fleet without the need to invest in new vehicles and technology . In this work we determine the optimal driving technique to minimize fuel consumption in a route. The results can be applied in training courses in efficient driving. For the calculations we use real data of a professional bus fleet. Then, we develop a consumption model and, using route optimization, we determine the driving technique that minimizes the consumption in the analyzed route. The results indicate that efficient driving has a very significant influence on fuel consumption. With optimum driving, reductions in consumption of up to 15 liters/100km (28% of reduction) could be achieved in the analyzed route. For the whole company, this is a significant reduction of consumption, considering the large distances covered by the professionals of the transport sector.Palabras Clave-Conducción eficiente, optimización de rutas, transporte profesional I. INTRODUCCIÓN Las técnicas de formación en conducción eficiente en flotas de transporte profesional están recibiendo mucha atención en los últimos tiempos. El consumo de combustibles fósiles hace del sector del transporte uno de los principales causantes de la emisión de CO2 y otras partículas contaminantes al ambiente. Para mitigar esta situación se puede mejorar la tecnología de los vehículos o hacer un uso más eficiente de la ya existente mediante programas de mantenimiento y técnicas de conducción eficiente. En las flotas de transporte profesional la opción más atractiva, y económica, es la utilización de técnicas de conducción eficiente ya que permite aprovechar la flota de vehículos existente sin necesidad de invertir en nuevos vehículos y tecnología. Para lograr una disminución relevante en el consumo de combustible es necesario formar adecuadamente a los conductores. Éstos controlan la aceleración, frenado, velocidad, rpms, marcha engranada, posición del vehículo en la calzada, por lo que su acción es determinante para lograr mejoras notables en el consumo de combustible y en la eficiencia medioambiental.Los programas de conducción eficiente orientados a la formación deben conseguir que el conductor sea capaz de acometer las acciones de conducción necesarias, adaptadas al vehículo y la vía, para realizar una conducción segura y con un menor consumo de combustible. La evaluación del programa de conducción eficiente se llevará a cabo mediante el rendimiento de los conductores que lo integran, bien mediante comparaciones simples de consumos de combustible o analizando las acciones de conducción. Como el consumo de combustible depende de muchos factores ajenos a la acción de conducción (temperatura, tráfico, carga, etc), la manera más justa de evaluar el rendim...
